I found this original 1950's pattern, in the university archive, so used this to help me draft my patterns.
There are similarities between this original pattern, and the one i plan to make, which made drafting easier for me.
But i didnt rely on it, didnt expect everything it to be identical.
Made some changes of my own, such as the jacket neckline, and the length of the jacket, and the skirt shape.
But it was a good starting off point.
